Vitamin B6

For your dog’s body to generate glucose, the nervous system to function correctly, and the red blood cells to be formed, he needs vitamin B6. This vitamin is also responsible for strengthening the immune system, gene activation, and niacin synthesis.

An example of a mushroom that is packed with Vitamin B6 is shiitake. 


Aids your body in making antioxidant enzymes that prevent damage to cells. Mushrooms such as portabella and cremini are packed with selenium. 

Vitamin D

In the approved quantity, vitamin D is vital as it helps a dog’s body regulate and retain phosphorus and calcium. Maitale is an example of a mushroom rich in vitamin D. 


Dogs, for example, German shepherds who love to swim, are energetic breeds. That’s why mushrooms are a vital part of their diets. Besides, the mushroom polysaccharides boost the growth of healthy bacteria in dogs. Normally, polysaccharides get to the colon unchanged, encouraging bacteria growth, which is good for your dog. 

Soluble Fiber

Some mushrooms, such as shiitake, are great for your dog because they keep cholesterol levels low. It’s the dietary fiber in these and other mushrooms that lowers the production of cholesterol. In addition, mushrooms block cholesterol absorption and minimize its levels in your dog’s bloodstream. 


Though it depends on which mushroom your dog eats, some mushrooms are low in sodium. Low sodium intake minimizes the chances of high blood pressure in dogs. Instead of buying store food with additives and salt, give your dog organic mushrooms to lower sodium intake. Otherwise, high sodium intake causes excess fluid retention in the body, resulting in high blood pressure in dogs. 

Besides, you don’t have to season mushrooms because they have a savory flavor, which your dog loves. So, adding salt or other flavors isn’t necessary. One cup of mushrooms contains only 4.8 mg of sodium, which is very low and healthy for your dog. 

Amino Acid and Antioxidants

At least 6 million dogs yearly are diagnosed with cancer. You can lower the chances of your dog falling victim by giving him mushrooms, and here’s why.

Mushrooms are ergothioneine-rich. This amino acid and antioxidant slows the damage to cellular cells. Mushrooms that have high ergothioneine include maitake, shiitake, and king oyster.

Add them in the correct quantity to your dog’s diet to minimize the chances of cancer.
